VELOCIPEDE.

SPECIFICATION forming part of Letters Patent No. 460,242, datedSeptember 29, 1891.

Application filed May 23, 1891 Serial No. 393,809- (No model.) Patentedin England September 9, 1889, No. 14,205, and

October 30, 1889, No. 17,215.

To all. whom, it may concern:

Be it known that We, GEORGE L. MORRIS and WILLIAM T. W ILSON, bothsubjects of the Queen of Great Britain, residing in the city of London,England, have invented certain new and useful. ImprovementsinVelocipedes, (for parts of which we have been granted patents in GreatBritain, Nos. 14,205 and 17,215, and dated, respectively, the 9th. ofSeptember, 1889, and the th of October, 1889,) of which the following isa specification.

Our invention relates to that class of velocipedes having two equal orapproximately equal sized wheels placed one in front of the other, thefront one being used for steering and the rear one for driving, suchmachines being technically known as Safety bicycles, and its objectsare, first, to provide a strong and rigid frame; secondly, toprovideasimple and easy method of adjusting the drivingchain; thirdly,to facilitate theadjustment of the ball-bearings wherever applied;fourthly, to facilitate the attachment of the drivingchain wheel and thecranks to the pedal-crank axle, so that they may readily and easily beattached to or removed from the said axle, and, fifthly, to provide ameans of attaching the pedal-pin to the crank, whereby the width of thetread may be materially reduced. lVe attain these objects in the mannerillustrated in the accompanying drawings, in

which- Figure 1, Sheet No. 1, is a view in side elevation of a Safetybicycle embodying our improvements. Fig. 2, Sheet No. 1, is aperspective view in side elevation, on an enlarged scale, of theimproved main frame. Fig. 3, Sheet No. 1, is a view in broken sideelevation, on an enlarged scale, of the chain adjustment; and Fig. 4,Sheet No. 1, is a view in plan of the adj listing-bolt thereof. Fig. 5,Sheet No. 2, is aview in sectional elevation of a pedal-crank-axlebracket audits fittings, showing the improved method of adjusting theball-bearin g and the improved method of attaching the cranks and thedriving-chain wheel to the pedal-crank axle and the pedalpinto thecrank. Fig. 6, Sheet No. 2, is a broken view in end elevation of thepedal-crank and axle with the washer and key removed, showing the keywayin the end of the axle and the ends of the bosses of the chain-wheel andcrank. Fig. 7 is a broken view in end elevation, showing the method ofattaching the pedal-pin to the crank. Fig. 8, Sheet No. 2, is a view inend elevation of the adjustable clip of the ball-bearing; and Fig. 9,SheetNo.

2, is a broken view in side elevation showing the application of theimproved adjustment to a ball-bearing head. Figs. 10 and 11. are 6:broken views in end and side elevation of a modification of our improvedmethod of attaching the cranks and chain-wheels to the pedaLcrank axle;and Fig. 12, Sheet No. 2, is

a broken View showing afurther modification of this part of ourinvention.

Throughout the several views similar parts are marked with like lettersand figures of reference.

Referring to Figs. 1 and 2 of the accom- 7o panying drawings, the mainframeA consists of eight essential parts, which are designated bynumbers. 1 and 2 are forks, the prongs of which are joined together andslotted to form smallforks a to receive the axle B of the driving-wheel.The crowns of these forks are connected by a segmental tube 3. From thejunction of the fork 2 and the segmental tube 3 a tube 4 runs forwardand upward and is joined to the lower end of the socket 5, forming partof the steering head or joint. From the junction of the fork 1 and thesegmental tube 3 a tube 6 runs forward and is joined to the top of thesocket 5. From the junction of the fork 1 and the segmental tube 3springs a short vertical tube 7, adapted to receive the stock of theseat-pillar, and across the angle formed by the tube 7 and the tube 6 adiagonal stay 8 is fixed. The bracket for carrying the bearings for thego pedal-crank axle is located at the junction of the fork 2 and thetube 4. A frame constructed on these lines may be made of tube ofexceeding light gage, as its members are so arranged as to give thegreatest rigidity 5 and strength to the whole structure.

Referring to Figs. 3 and 4, Sheet No. 1, of the accompanying drawings,in the small forks formed on the ends of the combined prongs of theforks 1 and 2 of the frame A IOO are cut or formed slots a, adapted toreceive the ends of the axle 13, carrying the drivingwheel. On each endof the axle B is placed a Washer 0, having a screwed shank a set off tolie within the slot h. On this screwed shank is threaded a nut D, havinga collar or rim 01 formed on it, adapting it to engage with slots orrecesses 60 formed in the prongs of the fork a. The nut D may be formedwith a square or hexagon head to enable it to be turned with a spanner,or it may be made with wings, forming a butterfly-nut, or the head maybe simply milled to enable it be turned by hand. To adjust the tensionof the driving-chain,the lock-nuts b b on the ends of the axle B areslackened and the adjusting-nuts D D rotated equally, thus impartingtravel to the screwed shanks c c of the washers G O, and so altering theposition of the axle B. After the necessary adjustment has beeneffected, the lock-nuts Z) Z? are tightened and the axle and washerslocked tightly to the frame A.

Referring to Figs. 5, 8, and 9 of the accompanying drawings, we form onthe outside of the adjustable cone E of a ball-bearing a split sleeve E,having lugs or ears 6 6, through one of which a screw 6 passes and isthreaded into the other. Round the sleeve E at its point of attachmentto the cone E and for i about half its circumference we cut or formallyused to lock the cone after adjustment.

Referring to Figs. 5, 6, 10, and 11 of the accompanying drawings, thecrank F is fixed to the pedal-crank a'xle G by means of a key H, adaptedto fit in a transverse keyway or sloth, cut or formed across the end ofthe axle and the boss of the crank. To keep the key H in position, ascrew'g is threaded into the end of the axle and may either bearindirectly on the key H, through a washer H, as shown by Fig. 5, ordirectly, as shown by Fig. 11. The key H and keyway h may be either madewith parallel sides, as shown by Figs. 5

and 6, or slightly tapered, as shown by Figs. 10 and 11. The washer Hmay be made in one piecewith the key H, as shown by Fig. 12. e fix theend of the pedal-pin J to the free end of the crank F by a key H, in thesame manner that the crank is fixed to the pedal-crank axle, as shown byFigs. 5 and 7.

When it is desired to make the drivingchain wheel K easily detachable,it is formed with an elongated boss or sleeve it, over which the crank Ftits, and both are then fixed to the axle G and to each other by the keyH, as hereinbefore described, as shown by Fig. 5 of the accompanyingdrawings. Fig. 12 shows a modification of this arrangement, in which theabutting faces of the bosses of the chain wheel K and crank F are halvedtogether and kept interlocked by the key H, which fixes the crank to theaxle, as hereinbefore described.

We wish it to be particularly understood that we do not limit ourselvesto the exact details of construction hereinbefore set forth andillustrated by the accompanying draw ings, but hold ourselves at libertyto make such changes and alterations as fairly fall within the spiritand scope of our invention.

WVe are aware that it is not new to make the main frame of a Safetybicycle of a diamond pattern nor to adjust the driving-chainv by movingthe axle of the driving-wheel in slots in the main frame, nor to makethe cranks and chain-wheel detachable from the pedal-crank axle, and wedo not claim these broadly; but

hat we do claim as our invention, and desire to secure by LettersPatent. is-
